The Committee shall advise the Director of the U.S. Geological Survey (USGS) on proposed earthquake predictions, on the completeness and scientific validity of the available data related to earthquake predictions, and on related matters as assigned by the Director. At the 1-day workshop on May 18, the Committee will discuss with scientific experts the evidence for and nature of episodic nonvolcanic tremor and aseismic creep events and their possible relation to seismic slip on the Cascadia subduction interface and will discuss with emergency managers how the aseismic slip events and other earthquake- related phenomena in Cascadia should be communicated to the public. At the meeting on May 19, the Committee will review the workshop findings and compose recommendations to the USGS on what type of public information might be most appropriate and effective when episodic tremor and creep events are detected, and the Committee will receive brief updates on previous discussion topics.
